Description

This security bulletin contains information about 4 vulnerabilities.


1) Incorrect calculation (CVE-ID: CVE-2022-23001)

CWE-ID: CWE-682 - Incorrect Calculation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an incorrect choice of sign bit when compressing or decompressing elliptic curve points. A remote attacker can cause a denial of service condition on the target system.


2) Improper Check or Handling of Exceptional Conditions (CVE-ID: CVE-2022-23002)

CWE-ID: CWE-703 - Improper Check or Handling of Exceptional Conditions

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the resulting output is not properly reduced modulo the P-256 field prime and is invalid when compressing or decompressing a point on the NIST P-256 elliptic curve with an X coordinate of zero. A remote attacker can perform a denial of service (DoS) attack.


3) Improper Check or Handling of Exceptional Conditions (CVE-ID: CVE-2022-23003)

CWE-ID: CWE-703 - Improper Check or Handling of Exceptional Conditions

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the resulting output is not properly reduced modulo the P-256 field prime and is invalid when computing a shared secret or point multiplication on the NIST P-256 curve that results in an X coordinate of zero. A remote attacker can perform a denial of service (DoS) attack.


4) Improper Check or Handling of Exceptional Conditions (CVE-ID: CVE-2022-23004)

CWE-ID: CWE-703 - Improper Check or Handling of Exceptional Conditions

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists when computing a shared secret or point multiplication on the NIST P-256 curve using a public key with an X coordinate of zero, an error is returned from the library, and an invalid unreduced value is written to the output buffer. A remote attacker can perform a denial of service (DoS) attack.
